Robustness and disturbances in public transport

Abstract

Network-based systems are at the core of our everyday life. Whether it is electronic networking, electricity grids or transportation, users expect the networks to function properly and provide a feeling of safety and security. However, there may be disturbances. In this paper, we consider disturbances in the context of public transportation. The focus in this respect is on public transport planning and operations. To classify and cope with disturbances, one can find many ideas, including robustness, resilience, vulnerability, disruption mitigation or delay management. We survey related streams of literature and put them into perspective. As a major insight we show that different strands of literature exist that may benefit from becoming better connected and intertwined. Together with recent advances in information technology and solution methods, more integrated problem settings incorporating robustness and disturbances can play a major role in future planning and operations.

Bus Bunching and Bus Bridging: What Can We Learn from Generative AI Tools like ChatGPT?

“…A comprehensive list of references on bus bunching can be found in [5] (see esp. Section 5.7 and Table 7 in that work).…”

“…In real-world public transport systems, we may be forced to focus on quite a few issues related to robustness and disturbances. A comprehensive survey on this topic is provided in [5]. Among the specific areas dealt with in this respect, we can find bus bunching and bus bridging.…”

Initialization of metaheuristics: comprehensive review, critical analysis, and research directions

“…Similar ideas also come up in case of problem settings, where disturbances need to be considered and related repair mechanisms might be applied, where a given (disturbed) solution is taken as initialization for the subsequent optimization process; see, for example, Ge et al. (2022) for some references.…”

“…For example, we refer to the case of transit network design (and frequency assignment), where a classical idea is to apply a route construction as a seed for improvement and then to apply some sort of route repair; see, for example, Iliopoulou et al (2019). Similar ideas also come up in case of problem settings, where disturbances need to be considered and related repair mechanisms might be applied, where a given (disturbed) solution is taken as initialization for the subsequent optimization process; see, for example, Ge et al (2022) for some references.…”

Exploring the mobility in the Madrid Community

“…Methods to extract a coarse-grained signature of the urban mobility networks have been suggested 1 , as well as procedures for dissecting the urban spatial structure 2 – 5 from human mobility patterns. The public transport networks have been thoroughly analysed 6 – 10 and so too have their travel demands 11 . The shared mobility services have also been investigated 12 – 14 .…”
